Sound familiar? That's possibly because those are the same specs as the Xperia Z2, released only six months ago. I won't argue here whether that's far too soon to refresh a flagship model (it definitely is), but the Z3 does at least have a few tweaks to freshen it up.

It's slimmer for one thing, with a narrower bezel too. Although the screen resolution hasn't increased, Sony reckons that the display is much more power efficient than 2K screens (as you'll get on the LG G3) so the Z3 can achieve up to two days of use from a single charge. That's a pretty good claim.

The phone is due to go on sale "globally" sometime from October although Sony is yet to confirm specific regional availability or prices.

The back of the phone is where you'll find the 20.7-megapixel camera. It's the same resolution as before, but it's a wider angle lens and Sony reckons it can shoot with ISO speeds up to 12,800 -- theoretically making it much better in low light conditions.

It's waterproof to a depth of 1.5 metres (4.9 feet) for up to 30 minutes, allowing you to get snap happy underwater. The screen won't work when wet, but there's luckily a physical camera button that will work in all conditions.

A neat feature is the ability to use the phone as a display for your PS4 games. Your console will still do all the processing, but as long as you're on the same Wi-Fi network, you can stream the content to play on your phone with a DualShock controller.
